摘要 针对60GHz RoF(光载无线网络)微微小区,提出了一种新的基于自适应扩展单元的切换方案,用于实现微微小区的无缝覆盖。自适应扩展单元就是动态地将用户当前所在小区及其周围相邻的小区虚拟地构建成用户当前的扩展单元,随着用户的移动,扩展单元也不断重新构建。通过建立仿真模型,验证了自适应扩展单元切换方案的低掉话率和丢包率。 We demonstrate a new handover scheme for seamless communication in a 60 GHz broadband picocell Radio-over-Fiber network. The handover scheme is based on the Adapting Extended Cell （AEC） constructing the extend cell of adjacent cells .AEC is reconstructed with the mobility of user. Through building the simulated model, the results suggest AEC have low packet loss rate and drop rate.
